. proveme'nts in Jail-Door-Operating Devices;

and I do hereby declare the following to be a full, clear, and exact description of the invention, such as ywill enable others skilled in the art to which it a'ppertains to make and usethe sitions of the parts.

My invention relates to means for manipulating a plurality of sliding doors, and has for its especial object to provide improved mechanism for opening and closing and for locking and unlocking, either singly or all together, a number of celldoors,.such as used in'jails, without requiring the operator to enter the corridor where the-cells are located.

To the above ends the invention consists of the novel devices and combinations of devices hereinafter described, and defined in the claims. A

The invention is illustrated in the accompanying drawings, whereinlike charactersindicate like parts throughout the several views.

`Figure 1"-is a view in side elevation, with some parts of thecasing removed, illustrating my invention applied to the ,cell-doors of a jail looking at the same from the corridor. Fig. 2 is a view corresponding, in the direction in which it is viewed and in the positions of the parts, to Fig. 1, but showing the parts on a larger scale and with some portionssectioned and with others broken away. Fig. 3 is a vertical section on the line-w3c3 of Fig. 2. Fig. 4 is a section on the line m4 m4 of Fig. 2. Fig.' 5 is a section' on the line Q15 x5 of Fig. 2. Fig. 6 is a section on the line x m6 of Fig. 2. Fig. 7 is a view corresponding to Fig. 2, but illustrating different positions of the parts. Fig. 8 is a vertical section taken approximately on the line 5108.908 of Fig. 7. Fig.y 9 is still another view corresponding to Fig. 2, but illustrating still different positions of the parts. Fig. 10 is still another view corresponding to Fig. 2, but illustratingstill other different po- Fig. 11 is a horizontal section on the line wu of Fig. 2. Fig. 12

is a section taken 4approximately on the line m12 @12 of Fig. 2; and Fig. 1.3 is a view corresponding to Fig. 2, but illustrating positions of the parts not shown in theother view.

The numeral 1 indicates the metallic front plate or wall of the cell-compartment, which is provided with doorways 2. that open into the corridor and are provided on the corridor side of the wall with metallic easings or doorframes 3. The doorways 2 are adapted to be -opened and closed by sliding metallic doors 11,

shown as constructed of sheet-metal plates. These doors 1 are provided at their upper extremities with vertically-projecting hangerbrackets 5, to the upper ends .ot which vare journaled groovedwheels 6, mounted to run freely over grooved rails 7, rigidly secured to' the wall-plate 1 above the doorways. (See particularly Fig. 11.) The rail- 7 so closely overlies the upper edges of the doors that the grooved wheels 6 cannot be forced laterally oli Jfrom the said rail. The lower extremities of the doors are guided in the usual way by i vthe'lower portion of the casing 3.

At corresponding edges the doors 1 are shown as provided with notched projections 8, which are herein termed lock-hooks. rFliese lock-hooks 8 work completely through perforations 9, (see Figs. 6 and 7 formed in the corresponding vertical portions ofthe door-easings 3, 1n which casings verticallymovable lock-bars 10 are mounted for cop-l eration with said lock-hooks to lock the doors in closed positions. As shown, the extreme lower ends of these lock-bars 1() are notched, so that when raised they will permit the free movements of said. lock-hooks, and hence of course of the said doors. When the said lockbars are lowered, however, while the doorsl are closed, theydrop into the notches of the hooks 8, as shown in Figs. 3 and 6, and lock the doors in their closed positions. These lock-bars 10 will be hereinafter designated as the primary door-locks to distinguish them.

IOO

tailed flange 12, formed on one of the hangerbrackets 5 of the corresponding door. (See particularly Figs. 2, 4, 5, and 8.) The lower ends of the lock-pieces 11 are, as shown, reduced and turned laterally to form lock-lugs 13, which are adapted to engage with either of a pair of fixed detents afforded by notches 14 and 15, cut in a bar 16, shown as rigidly secured to a horizontally-extended channellike guide 17, rigidly supported from the wallplate .1. I(See particularly Fig. 4.) The detent-notches 14 are so positioned that the lugs 13 of the lock-pieces 11 may engage therewith when the doors are closed and the said lockpieces are lowered. On the other hand, the detent-notches 15 are so located that the said lock-lugs 13 of the lock-pieces 11 will be engaged therewith when the doors are open and the said lock-pieces are lowered. rlhese lockpieces or secondary locks, it will therefore be seen, will serve to lock the doors both in opened and in closed positions. The secondary locks 11 are mounted to travel with the doors; but at their upper ends they maintain constant engagement with the movable portions of corresponding hails 18, which bails extend in a horizontal plane and are pivotally attached to bearings 19, secured on the wallplate 1. (See particularly Figs. 2, 4, and 11.)

For each door there is a vertically-movable cam-head 20, so called. These cam-heads, as shown, have vertically-extended portions, which work through bearings 21 on the wallplate l. (See particularly Figs. 2 and 3.) The depending portion of each cam-head 20 is connected to and, as shown, interlocks with the upper end of one of the primary locks or lock-bars 10. Such interlocking engagement is best shown at 22 in Fig. 3. Furthermore, each cam-head 20 is provided with a bifurcatcd projection 23, which, as shown, acts upon a projecting end of the corresponding bail 18. Hence vertically-upward movements of the cam-heads 2O will raise both the primary and secondary locks, thereby simultaneously renderingboth of the said locks inoperative to lock the said doors. 1t will be further noted that the said bails will operate to lift the said secondary locks 11 regardless of the positions of the d oors--that is, whether the said doors be in closed positions or in extreme open positions. The two cam-heads have differential cam surfaces or grooves of different arrangement and which bear a peculiar relation to each other, which will presently be noted and particularly set forth in the description of the operation. It should here be noted, however, that the left-hand or first cam-head 2O has a camgroove constructed with alternately-reversed inclined cam-sections 23a, 23", and 23C, and that the right-hand or second earn-head 2O has a cam-groove formed with an upper horizontal section 24", an inclinedV intermediate section 24", and a lower horizontal section 24C.

A long horizontally-extended door-operating bar 25 is mounted to slide through a koepel'- guide 26 on the wall-plate 1 and is guided by the channel-like support 17 heretofore noted, and is thus held in position immediately overlying' the lock-lugs 13 of the secondary locks 11. This door-operating bar 25 is provided with detents or notches 27, which in the normal position of the parts (shown in Fig. 2) immediately overlie and aline with the locklugs 13 of the secondary locks 11. The lefthand end of the bar 25, as viewed in Fig. 2, is pivotally attached to the lower end of an extensible oscillating lever made up of telescoping sections 28 2S). The upper lever-section 28 is pivoted at 30 to the wall-plate 1,

land the pivotal connection between the leversection 29 and the bar 25 is made by a stud 31, which works in a slot 32 of the keeperguide 26. The intermediate portion of the member 29 is connected by a link 33 to an operating-lever 34, located outside the corridor and, as shown, pivoted to a bearing 35 on the wall-plate 1. Near its free depending end the lever 34 is perforated at 36 to pass therethrough a staple 37, rigidly secured, as shown, to the left-hand extremity of the wallplate 1. A padlock (not shown) is adapted to be applied to this staple 37 to lock the lever 34 in normal position. (Indicated in Fig. 2.) Attention is here also called to the fact (see particularly Fig. 6) that the lock-hook 8, which is carried by cach door, as shown, is perforated at its outer end so as to permit of the application thereto of a padlock to lock the door closed with additional security.

A lock-actuating bar 38 is mounted t'o slide horizontally through bearings 39 and through the bearings 19 heretofore noted, which bearings are rigidly secured vto the wall-plate 1. This bar 38 is provided with cam-pins 40, which work in the cam-grooves of the camheads 20. At its left-hand end the sliding bar 38 is connected by a link 41 to an operating-lever 42, located outside of the corridor and, as shown, pivoted to a bearing 43, secured to the adjacent extremity of the wallplate 1. The lever 42 has a latch 44; which cooperates with the notched latch-segment'l 45, rigidly secured to the adjacent extremity of the wall-plate 1.

In the construction illustrated only two sliding doors are shown as arranged to be moved by the sliding bar 25 and to be locked and unlocked under the control of the sliding bar 38, although in practice a larger number of doors may be controlled thereby. lVith the said arrangement described the lock-actuating bar 38 is adapted to be set in four dil'- ferent positions to accmnplish four dili'erent results, and hence the lock-segment 45 is provided with four lock-notches, adapted to cooperate with the latch 44 and lever 42 to lock the said bar 38 in any one of the said four positions.

In the normal positions of the parts shown in Figs. 1, 2, 3, and '4 the doors are closed and are locked both by the primaryl and the secondary lock and 11, respectively, which locks are then lowered. This normal position of the lock-actuating bar 38 will be turned to its irst position, and in such position, it will be noted, that the left-hand cam 40 engages the left-hand extremity of the cam-section 23, while the right-hand cam-pin 40 engages the left-hand extremity of the horizontal slotsection 24a. By these engagements the primary lock-bars 10 are' positively held down in interlocking engagement with the lock-hooks 8 of the doors, and the secondary locks 11 are positively held down with their lock-'lugs 13, engaged with vthe detent-notches 14 of the bar 16. Fig. 7 illustrates the second position of the lock-actuating bar 38, and in this position of the parts it will be seen' that the left-hand cam-pin 40,v acting on the inclined cam-slot section 23, has raised the left-hand cam-head and the saidjcam-head has raised the lefthand primary lock-bar 10 into an inoperative position, and lthrough the left-hand bail 18 has raised the left-hand secondary lock 11 into such position that its lock-lug 13 has been carried out of engagement with the stationary detent 14 and into engagement with theoverlying lock-notch 27y of the door-actuating bar 25. By the above-noted action the left-hand door is unlocked from the door-casing'and stationary supports and is coupled or locked to the door-actuating bar 25. The first step of movement of the lock-actuating bar 38, above noted, carries the right-hand cam-stud 40 to the right-hand extremity of the horizontal slot-section 24 without imparting movement to the right-handcam-head 20. Hence whenA the said bar 38 is moved to its second position the right-hand door still remains locked in its closed position. If now the door-actuating bar 25 be moved toward the right by means of the leverv34, the left-hand `door alone vwill be carried withv the said bar 25. Referring now to Fig. 9, which illustrates the third position of lock-actuating bar 38, it will be noted that the left-hand cam-stud 40, acting A on the cam-groove section 23h, has again forced downward the left-hand cam-head 20, and hence has forced downward the left-hand primary and secondary lock and locked the left-hand door in its closed position, while, on the other hand, the right-hand cam-stud 40,

' acting on the cam-section 24b of the right-hand cam-head 20, has positively raised said righthand cam-head and raised the right-hand primary and secondary locks, thus unlocking `ing bar 25.

moved toward the right both doors will bey `locks are raised, thereby unlocking both of the doors from their fixed supports and locking or coupling the same to the door-actuat- Hence if the said bar 25v be now.

moved therewith into or toward extreme open positions. From what has been said it will and slide over .the bails 18 into positions -in ,which the lock-lugs 13 of said locks directly' `overlie the detent-notches 15. evident that if, whileboth doors are in their be of course clear that when the doors are moved from their closed to their open 'posi tions the secondary locks 11 move therewith.

Hence it is eXtreme open positions, the'lock-actuating bar 38 be moved back toits normal position,

as indicated in Fig. 13, both doors. will,.by `,the so-called secondary locks, be locked in their open positions.; Furthermore, ifthe said lock-.actuating bar be moved back to` its y 'y normal or first position while one of the doors is open and the other is closed the said doors.

will be locked in such positionsvto wit, the one in an open position and the other in its closed position.

From the foregoing description and statements made it is evident that by the manipu. lation of the two levers 34 and 42 the doors may be locked and unlocked and opened and close-d in any desired order, and, furthermore,

that when locked in closed positions they are.

locked with great security, both by the primary and by the secondary locks. The extensible link or lever connection 28 29, as is evident,multiplies the movemement of the.

llink 33 nearly two to one and, furthermore,r .is easily operated, is of simple constructiom and is strong and durable.

Where more than two doors are to be op- IOO erated by a common door-actuating bar and by a common lock-actuating bar, it is of course evident that the cam-surfaces of thev several cam-heads 2O or equivalent devices, while constructed on the same plan, as herein illustrated, must be carried out or continued in several instances.

The construction illustrated has been built and tried and has proved extremely satisfactory for the purposes had in view. v

From what has been said it will of course be understood that the mechanism described is capable of modiiication Within the scope of my invention, as herein set forth and claimed. lt will also be understood that many of the terms herein used-such. for instance, as door-actuating bar, lock-actuating bar,

primary lock, secondary lock, &c.--are IIO used in a broad sense and not in a sense in any wise tending to limit the said devices to the specific construction shown.

What I claim, and desire to secure by Letters Patent of the United States, is as follows:

l. In a device for manipulatinga plurality of sliding doors, the combination with a sliding-dopr-actuating bar and a sliding lock-aetuating bar, of locks for locking said doors in closed positions, lock-actuating cam-heads for the several ldoor-locks, having dierential cam grooves or surfaces, and cam projections on said lock-actuating bar, cooperating with said cam grooves or surfaces, said cam grooves or surfaces operating to release said locks under different movements of said lock-actuating bar, substantially as described. 2.
